1. Balo's Concentric Sclerosis with Acute Presentation and Co-Existing Multiple Sclerosis-Typical Lesions on MRI
Case Rep Neurol 2015;7: DOI: /
Fig. 1.a Axial T1W MRI (baseline MRI) shows a 2 cm sized well-circumscribed hypointense lesion in the left centrum semiovale. b Corresponding axial T2W MRI shows ill-defined concentric bands within the lesion. There is minimal peri-lesional oedema. c Corresponding contrast-enhanced coronal T1W MRI shows concentric enhancement within the lesion, which is pathognomonic of BCS. d Corresponding axial FLAIR image shows the Balo lesion along with a simultaneous small ovoid hyperintense lesion in the left peri-trigonal white matter. These findings indicate associated MS.

2. Balo's Concentric Sclerosis with Acute Presentation and Co-Existing Multiple Sclerosis-Typical Lesions on MRI
Case Rep Neurol 2015;7: DOI: /
Fig. 2.a Axial T2W MRI (follow-up MRI at 4 months) shows very well delineated concentric rings within the Balo lesion. No peri-lesional oedema is seen. b Corresponding contrast-enhanced axial T1W MRI shows interval regression of the previously noted contrast enhancement within the lesion.
